U.S. Marine Force Recon vs. Canadian Light Infantry

S1 E5: Three teams of elite warriors -- the U.S. Marine's Force Recon, the Canadian Light Infantry, and a "Rogue" Squad of private contractors -- slug it out. They test their combat skills with an arsenal of weapons: from knives and pistols to sniper and assault rifles and submachine guns -- not to see who's best with a single weapon, but to see who's best with them all.
